Bella's Hair Colour (Patreon)

Hi everyone. I've been going back and forth trying to make a decision on a future chapter for Maid for Pleasure and I'm struggling to choose which option to go with. So I thought that since I can't decide, I'll let you guys, my lovely fans, help me make the choice.
For a bit of context, Isaac will be getting a complete makeover at a hair salon in a future chapter and I'm tossing up between Bella keeping her blonde hair colour, or moving towards a brunette that is closer to Isaac's natural brown colouring.
What do you guys think? Your choice will determine whether Bella stays a blonde or goes to her natural hair colour.
PLEASE NOTE: The style might change for the actual pages, this is a concept/example of what the brunette hair would look like next to the blonde.
